I have a standard order form that has a number of fields where the quantity (number )is typed in They are labelled qty1, qty2 and so on.
Some of the items on the order form attract an additional fixed one off charge which is shown in a separate field call it addcharge.
If qty1 has a number entered it attracts an added charge and the addcharge field alters value from nil to say 1
If qty2 has a numbered entered no additional charge applies
If qty3 has a numbered entered no additional charge applies
If qty4 has a number entered it attracts an added charge and the addcharge field alters value from nil to say 1 or if the previous qty1 has already altered the addcharge field to 1 it stays at 1.
If qty5 has a number entered it attracts an added charge and the addcharge field alters value from nil to say 1 or if the previous qty1 and qty4 has already altered the addcharge field to 1 it stays at 1
It seems to me that some "if else" activation javascript is needed along the lines of "if field qty1 is greater than 0 the field addcharge is 1" and I assume the script should be placed in every qty field that attracts addcharge.
Can any one help with the script please.
Thanks Eric
